When using 2-way communication between 2 RF modules, it is very useful to be able to detect loss of communication between the modules. Especially with remote sensing applications, you don't want to ...

Wireless data transmission enables many applications (e.g., in the field of home automation). However, the communication must be robust and reliable. This nRF24L01+-based PIR sensor project is a basic ...

An Arduino and a data radio can make a great remote sensor node. Often in such situations, the hardware ends up installed somewhere hard to get to – be it in a light fitting, behind a wall, or ...
